−
−	Swestore-dCache is distributed across the SNIC centres [http://www.c3se.chalmers.se/ C3SE], [http://www.hpc2n.umu.se/ HPC2N], [http://www.lunarc.lu.se/ Lunarc] and [http://www.nsc.liu.se/ NSC]. Data is stored in two copies with each copy at a different SNIC centre. This enables the system to cope with a multitude of issues ranging from a simple crash of a storage element to losing an entire site while still providing access to the stored data.
−
−	One of the major advantages to the distributed nature of Swestore is the excellent aggregated transfer rates possible. This is achieved by bypassing a central node and having transfers going directly to/from the storage elements if the selected transfer protocol allows it. Swestore can achieve aggregated transfer rates in excess of 100 Gigabit per second, but in practice this is limited by connectivity to the end user, each university or a limited number of files (typically max 1 Gbit/s per file/connection).
−
−	~~To protect against silent data corruption the dCache storage system checksums all stored data and periodically verifies the data using this checksum.~~
−
−	~~The dCache system does NOT yet provide protection against user errors like inadvertent file deletions.~~
−
−	~~== Basic information ==~~
−
−	~~For basic information on how to apply for storage or become a member of an existing project and managing your storage username/password, please check the main [[Swestore]] page.~~
−
−	~~== Acquire and manage certificate (for users accessing with certificate authentication) ==~~
−
−	~~Certificate authentication is needed in some special cases, and more convenient for use in automation (ie. Robot certificates).~~
−
−	~~Some communities require certificate authentication and such users might already have a certificate, that certificate is likely good to use with Swestore.~~
−
−	~~If you need to use Certificate authentication, follow the instruction on the page [[Certificate Setup for Swestore]].~~
−
−	~~= Using Swestore =~~
−	~~== Download and upload data ==~~
−	~~=== From the command line ===~~
−
−	~~There are several command line tools capable of using the protocols provided by Swestore. For usage on SNIC clusters we recommend using the ARC tools which should be installed on all SNIC resources.~~
−
−	~~As an integration point for building scripts and automated systems we suggest using the curl program and library.~~
−
−	~~:; Interactive tools~~
−	~~:: Best suited for interactive use with various support for directory listings, wildcards etc.~~
